Asthma is a hereditary disease associated with IgE-mediated reaction. Whether maternal atopy and paternal atopy have different impacts on perinatal IgE production and asthma development remains unclear. This paper reviews and summarizes the effects of maternal and paternal atopy on the developmental aspects of IgE production and asthma. Maternal atopy affects both pre- and postnatal IgE production, whereas paternal atopy mainly affects the latter. Maternally transmitted genes GSTP1 and FceRI-beta are associated with lung function and allergic sensitization, respectively. In IgE production and asthma development, the maternal influence on gene-environment interaction is greater than paternal influence. Maternal, paternal, and/or postnatal environmental modulation of allergic responses have been linked to epigenetic mechanisms, which may be good targets for early prevention of asthma.

Secondary hyperparathyroidism may worsen after the administration of pamidronate in postmenopausal hemodialysis (HD) patients. The aim of this study was to evaluate the short-term effect of coadministration of calcitriol and pamidronate on dynamic parathyroid hormone (PTH) secretion. Fifteen postmenopausal women undergoing regular HD with serum intact PTH levels of >200 pg/ml were enrolled. The PTH-ionized calcium (iCa) curve was evaluated by the response to hypo- and hypercalcemia induced with 1 and 4 mEq/l of dialysate calcium, respectively. Parameters were compared after pamidronate was administered and after coadministration of pamidronate and calcitriol. Changes in serum levels of maximal serum PTH (PTHmax), basal PTH (PTHbase) and minimal PTH (PTHmin) were evaluated. Pamidronate therapy resulted in a decrease in predialysis basal plasma iCa (p < 0.05) and an increase in PTHmax (p < 0.01), PTHbase (p < 0.01) and PTHmin (p < 0.01). The change in serum iCa and PTH was reversed after the coadministration of calcitriol and pamidronate. Our study demonstrated that pamidronate therapy is associated with a reduced plasma iCa and increased PTH secretion. These adverse effects may be reversed by calcitriol. These findings suggest that in considering pamidronate treatment in postmenopausal patients with osteoporosis receiving HD, it might be safer to add calcitriol to prevent the increased PTH secretion.

Background: A better description of the clinical and laboratory manifestations of fatal patients with dengue hemorrhagic fever (DHF) is important in alerting clinicians of severe dengue and improving management. Methods and Findings: Of 309 adults with DHF, 10 fatal patients and 299 survivors (controls) were retrospectively analyzed. Regarding causes of fatality, massive gastrointestinal (GI) bleeding was found in 4 patients, dengue shock syndrome (DSS) alone in 2; DSS/subarachnoid hemorrhage, Klebsiella pneumoniae meningitis/bacteremia, ventilator associated pneumonia, and massive GI bleeding/Enterococcus faecalis bacteremia each in one. Fatal patients were found to have significantly higher frequencies of early altered consciousness (≤24 h after hospitalization), hypothermia, GI bleeding/massive GI bleeding, DSS, concurrent bacteremia with/without shock, pulmonary edema, renal/hepatic failure, and subarachnoid hemorrhage. Among those experienced early altered consciousness, massive GI bleeding alone/with uremia/with E. faecalis bacteremia, and K. pneumoniae meningitis/bacteremia were each found in one patient. Significantly higher proportion of bandemia from initial (arrival) laboratory data in fatal patients as compared to controls, and higher proportion of pre-fatal leukocytosis and lower pre-fatal platelet count as compared to initial laboratory data of fatal patients were found. Massive GI bleeding (33.3%) and bacteremia (25%) were the major causes of pre-fatal leukocytosis in the deceased patients; 33.3% of the patients with pre-fatal profound thrombocytopenia (<20000/μL), and 50% of the patients with pre-fatal prothrombin time (PT) prolongation experienced massive GI bleeding. Conclusions: Our report highlights causes of fatality other than DSS in patients with severe dengue, and suggested hypothermia, leukocytosis and bandemia may be warning signs of severe dengue. Clinicians should be alert to the potential development of massive GI bleeding, particularly in patients with early altered consciousness, profound thrombocytopenia, prolonged PT and/or leukocytosis. Antibiotic(s) should be empirically used for patients at risk for bacteremia until it is proven otherwise, especially in those with early altered consciousness and leukocytosis. © 2012 Lee et al.

Psoriasis is a chronic autoimmune skin disease with both environmental and genetic risk factors. Previous studies of the association between psoriasis and PTPN22 C1858T (rs2476601), a gain of function variant associated with a stronger inhibitory effect of T-lymphocytes, have produced inconsistent results. The purpose of the current study is to evaluate the association between PTPN22 C1858T and psoriasis using meta-analysis to: (1) have a sufficient sample size for detecting a weak association; and (2) to explore the heterogeneity between studies. A meta-analysis based on random-effects model was performed with ten studies (3,334 psoriasis cases and 5,753 controls) identified from a literature search. A non-significantly positive association between psoriasis and the PTPN22 T1858 was observed [summary allelic odds ratio (OR) = 1.15, 95 % confidence interval (CI): 1.00-1.33] and the association appears stronger among subjects with psoriatic arthritis (summary allelic OR = 1.23, 95 % CI: 1.00-1.52). A null association between PTPN22 T1858 and early-onset psoriasis was observed (summary allelic OR = 1.08, 95 % CI: 0.92-1.28). The current analysis showed a non-significantly positive association between psoriasis and the PTPN22 T1858 allele, and the association appeared stronger among subjects with psoriatic arthritis. Future studies of psoriasis should incorporate gene-environment interaction in the analysis and pay attention to the heterogeneity of psoriasis cases and bias associated with population stratification. © 2012 Springer Science+Business Media B.V.

Gastrointestinal symptoms in Henoch-Schönlein purpura (HSP) are common and occur in about two-thirds of HSP patients. Surgical intervention is only required in a minority of cases. Intussusception is a rare complication and the most common surgical indication for HSP. We report a 3-year-old boy with HSP and clinical manifestations of palpable skin rash lasting for 4 days, fever for 3 days, intermittent abdominal cramping pain, and left ankle arthralgia lasting for several hours. Abdominal sonography revealed characteristic signs of intussusception including a doughnut sign and a pseudo-kidney sign in the right upper quadrant of the abdomen. After unsuccessful initial reduction by air enema, surgical reduction was arranged and manual reduction of the ileocecal intussusception without bowel resection was carried out. © 2010 Taiwan Pediatric Association.
